John R. “Jack” Martin has had some tough cases, but he’s never had to go to court blindfolded.

Martin represents convicted child killer Wayne Williams in a habeas appeal and was the trial lawyer for Abdul Al-Amin, aka H. Rap Brown, the former Black Panther turned Muslim imam who was convicted for the 2000 murder of a Fulton County, Ga., deputy. He also offered an unsuccessful defense of Carl Isaacs, who was put to death for his role in the 1973 slayings of six members of a rural Georgia family.
